Boy’s death from bat virus sparks calls for action to reduce flying fox populations

THE mother of a Cairns boy who died from lyssavirus on Friday has said no one should have to suffer the bat-borne virus’ deadly effects.

Ed Rybicki‘s insight:

And so the inevitable happens, and a sick little boy dies – from Australian bat lyssavirus infection.

Now, while I keep going on about "flying rats", one needs to get the "bat threat" in perspective: ONE child died in recent history due to a bat-borne rabies-like virus, and FOUR people since 1994 of bat-borne Hendra virus.  Yet people are calling for a cull: that’s right up there with the "kill all Great White Sharks" campaigns there have been over the years, for a threat of death of injury that is considerably less than you expereince every morning driving to work.

US bird flu research to resume under new restrictions

Back in January 2012, the US government announced it was joining with scientists around the world and temporarily suspending research on the deadly pathogen H5N1, also known as avian flu or “bird…

Ed Rybicki‘s insight:

" "the policy aims to preserve the benefits of life sciences research while minimizing the risk of misuse.""

 

OK – can’t argue too hard with that, I suppose?  EXCEPT that it probably limits access to the research of countries where the virus is ACTUALLY a problem.

Pulse polio vaccine administered

As a part of pulse polio immunisation programme, over 5.63 lakh children below five years including new born babies were administered with oral polio vaccine in  the twin cities and cantonment area here on Sunday….

Ed Rybicki‘s insight:

Just shows you the sheer scale of the effort – nearly a million babies in ONE district in India! – still needed to contain a virus that was almost eradicated.  Almost, that is, until politics and selfish policies made people in neighbouring Pakistan suspicious of vaccinators.

A geographic analysis of population density thresholds in the influenza pandemic of 1918-19

25 February, 2013

See on Scoop.itVirology News

Geographic variables play an important role in the study of epidemics. The role of one such variable, population density, in the spread of influenza is controversial.

Prior studies have tested for such a role using arbitrary thresholds for population density above or below which places are hypothesized to have higher or lower mortality. The results of such studies are mixed.

The objective of this study is to estimate, rather than assume, a threshold level of population density that separates low-density regions from high-density regions on the basis of population loss during an influenza pandemic. We study the case of the influenza pandemic of 1918–19 in India, where over 15 million people died in the short span of less than one year.

Ed Rybicki‘s insight:

This is an interesting paper, because it is one of the ONLY ones I have ever seen that analyses ANYTHING to do with the 1918 H1N1 pandemic, that comes from a developing country.  Moreover, it makes what I think is possibly quite a valuable contribution to "health geographics", especially for high-denisty low-income populations.

I also note that 15 MILLION PEOPLE were estimated to have died in India ALONE: this is close to the old estimate for the WORLD total (20 million), which was revised upwards to 50-100 million after developing country stats were taken into account, in the late 1990s.

Makes you think what a new version might do….
